PAPER-BEATING ENGINE.

Specification of Letters Patent.

Patented Jan. 26, 1909.

Application filed April 23, 1908. Serial No. 428,762.

To all whom "it may concern:

Be it known that I, LOUIS JonenNsEN, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Paper- Beating Engines, of which the following is a specification.

My invention relates to a new and useful improvement in paper beating engines, and has for its object to provide the exceedingly simple and efl'ective device of this character by means of which the beater knives upon the beater roll as they wear away may be brought closer to the back-fall so that the space between the said back-fall and the knives will be generally the same, thus producing a uniform material over which the paper is to be made.

A further object of my invention is to provide a sup lemental floor for the beating engine whic may be easily taken out and when same is worn out or been eaten away, as is the case when strong acids are used, and a new one put in its place.

A still further object is to provide a valve for the sand pit which will allow all other foreign substance to be Washed out of the it without turning off all the water, as is t e case to-day.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention a pertains may understand how to make and use the same, I will describe its construction in detail, referring by letter to the accompanying drawing, in which the figure is a perspective view of a beatin engine showing my improvements secure thereto, a portion of the beater wall and floor being broken away.

In carrying out my invention as here embodied, A represents a beating en ine which may be of the ordinary shape an size having the back-fall B therein. Formed with the heater or placed beside the same are lighter posts C to which is adjustably secured the lighter bar H.

K indicates lugs formed upon the lighter bar H through which are threaded the adjusting bolts L and L.

M indicates longitudinal slots cut in the lighter bar.

N represents the slidin bearing through which pass the bolts 0 sai bolts also passing through the slots M thus allowing the sliding bearin N to be moved in a straight line to one sic e or the other.

The inner ends of the adjusting bolts L and L are adapted to rest against the sliding bearing N, and when one of the said adjusting bolts is threaded in and the other out the adjustable bearing will be moved accordingly.

The heater roll P on the periphery of which is placed the beater knives Q has a shaft R passing through the center thereof and resting in the adjustable bearing N.

A indicates a permanent floor of the beating engine and B the sup lemental floor which would be laid on top 0 the permanent floor and held thereto by wooden pegs, nails, or screws. This supplemental floor will be made of some hard wood, and as free as ossible from knots, so as to produce a long ived floor, but when it is worn out the same may be readily removed and the new one substituted.

C indicates a sand pit beneath the floor of the beating engine, into which sand and other foreign substances will enter through the grate D. The bottom and sides of the sand pit would all slope toward one point, and to this point I place a bell shaped valve E, the lower end of its stem F, being connected to one end of the swinging lever G, which is pivoted at G.

H indicates a plunger which passes through the floor and is secured to the opposite end of the swinging lever G, thus it will be seen that by pressing the plunger H downward it will open the valve E, and as the water passes over the beating engine to the outlet, it will wash the sand or other foreign substances from the sand pit, thus doing away with having to lift the grate D from its position and shoveling the sand out as is the case with all the heaters of to-day.

In practice as the material which is to be crushed passes between the back-fall and the knives it gradually wears away said knives, thus leaving a larger space between the knives and the back-fall than when the knives were new, and this causes larger particles of the material to pass into paper thus making a paper which is not of uniform quality, and by the use of my adjustment this is wholly overcome because as the knives wear away they will be brought closer to the back-fall by threading outward the adjusting belt' L and threading inward the adjusting belt L thus moving the sliding bearing to that side which will bring the knives closer to the back-fall.

Of course I do not wish to be limited to the exact details here shown as these may be varied without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful, is

1. In combination with a beating engine, posts formed therewith, a lighter bar having longitudinal slots formed therein, lugs hav ing threaded openings cut in the same formed upon the upper surface of said lighter bar, a sliding bearing adapted to rest upon the lighter bar between said lugs, belts passing through said sliding bearing into the longitudinal slots, adjusting bolts passing through the lugs and resting upon the sliding bearing, a beater roll, a shaft passing through the center of said beater roll the ends of which rest in the sliding bearing, beater knives se cured to the periphery of said beater roll, the supplemental floor secured upon the permanent floor, a sand pit fastened beneath the floor of the beating engine, a grate placed over said sand pit, thus allowing sand or other foreign substances to pass from the paper making material into the sand pit,

a bell shaped valve secured to the bottom of said sand pit, a swinging lever, one end being secured to the lower end of the valve stem, and a plunger secured to the opposite end of the swinging lever, and passing upward from the floor, thus providing means for opening the valve, as shown and described.

2. In combination with a beating engine, lighter posts formed therewith, a lighter bar having lugs formed thereon, the ends of which are adjustably secured to the lighter posts, a sliding bearing resting upon said lighter bar, means for moving it from one side to the other, a heater roll having knives secured upon its periphery, a shaft passing through the center of said beater roll the ends of which rest Within the sliding bear-' ings, a supplemental floor secured upon the permanent one and sand pit fastened beneath the floor of the beating engine, and

means for allowing sand or other foreign substance to be washed therefrom, as shown and described.

In testimony whereof, I have hereunto affixed my signature in the presence of two subscribing witnesses.

LOUIS JORGENSEN.
